Here is one for our Antipodean friends.
I have just acquired this round on flea bay so I do not have any provenance for it. The upper part of the headstamp is very faintly stamped but appears to be CAC VIIZ 20. The round has been inerted and has come from an old collection or display as the case and bullet are lacquered and the case bears the number 977.
I have a checklist from Lynn Harris that shows VIIZ production at CAC starting in 1921, so is this 1920 dated example previously known? Also, as it has no month in the headstamp I presume this is NZ and not Australian production?
